The ARRT Limited Scope Test is separated into 5 different modules. The main portion, which will be addressed in this module, is called the Main Core Module by the ARRT. Questions focus on radiation biology, radiation protection, and almost everything we have covered that doesn't specifically have to do with anatomy and x-ray positioning. That comes in the other modules. The questions may cause a little frustration, but they are designed in the same manner you will be exposed to when you sit for your ARRT exam.
